Described on the site as “relaxation room for man and woman,” Cozy Room's human-sized box contains a desk, some shelves, and little else.

Apparently, would-be introverts slide into the cubicle using the high-backed chair supplied, and become completely encased from all angles.

Once inside, customers can enjoy the use of whatever they've put inside their cubicle – a TV, computer games, or a healthy bottle of bourbon – safe in the knowledge that no pesky outsiders can disturb their alone time.
